摘要:
An embodiment of an apparatus includes a centrifugal drive unit, an arm assembly, an optional dynamic balancing ring, and a workpiece fixture. The arm assembly is operatively connected to the centrifugal drive unit and configured to revolve about a primary axis perpendicular to the arm. The workpiece fixture is mounted to the arm assembly, and is configured to rotate at least one workpiece about at least one secondary axis outboard of the primary axis.

An invention is provided for creating smoothed, heat-treated glass fragments. The invention includes placing a plurality of heat-treated glass fragments into a tumbling or vibrating apparatus. Each heat-treated glass fragment is formed from glass that has been heated to a temperature of at least 1000° Fahrenheit and rapidly cooled to a temperature below 700° Fahrenheit. The plurality of glass fragments are then tumbled or vibrated for a predetermined period of time such that surfaces of the heat-treated glass fragments are smoother than prior to tumbling. The glass fragments are thereafter removed from the tumbling apparatus, resulting in smoothed, heat-treated glass fragments that are suitable for direct handling without hand protection.

A wheel finishing apparatus includes an upwardly opening tank which stores therein a water and media mixture. An elongated spindle is mounted on a frame and is displaced directly above the tank. The spindle includes on its lower end a hydraulically expandable bulb which acts as a wheel clamp to releasably mount a wheel to be finished onto the spindle. A circular plate is mounted on the spindle a predetermined distance from the lower end of the spindle and cooperates with a mounted wheel to define a cylindrical flow channel therebetween. A motor connects to the spindle and operates to rotate the spindle and thus the wheel in the media at high speeds.
摘要:
An apparatus for polishing medals for a game machine, and for separating an abrasive from the medals. An intake port (2) for the medals and the abrasive is provided on the lower end side of a polishing pipe (1) set upright, while a medal delivery port (3) is provided on the upper end side. A rotatable screw element (4) is mounted inside the polishing pipe (1) so as to lift up the medals and the abrasive while stirring them. A separation unit (A) which separates the abrasive from the medals and which feeds the separated abrasive to the intake port (2), is joined to the upper part of the polishing pipe (1).
摘要:
A method and apparatus for cleaning photoreceptor substrates where at least one substrate is rotated in a bath of moving dry ice particles. The dry ice particles contact the outer surface of the substrate, melt locally upon contact and refreeze to capture particulate contaminants on the outer surface of the dry ice particles. An inert gas counter current to the flow of moving dry ice particles is supplied to enhance cleaning efficiency and assist in removing carbon dioxide, contaminants and small dry ice particles.
摘要:
A substantially tubular elastic housing member is adapted to surround an elongated element in close proximity thereto and adapted to contain a finishing medium therebetween. A sonic oscillator is coupled to the elastic housing member to resonantly vibrate said member as the elastic member and elongated element are axially moved relative to one another.
